ABSTRACT
Purpose : We studied the correlation between urinalysis and radiologic findings in infants and children with urinary tract infection. Method : Urine Dipstick test and unstained urine microscopic examination were carried out in 56 infants and children who were hospitallized with the diagnosis of urinary infection by pocitive urine culture at Seoul Adventist from September 1996 through August 1998. Urine was collected by midsream, catheter, urine bag after cleansing or bladder puncture. Renal sonography and $^{99m}Tc-DMSA$ renal scan or voiding cystoureterography were studied.
Results : 1)In dipstick analysis, leukocyte esterase(LE) were positive in 30 cases of 56 patients(54%) and Nitrite were positive in 20 cases of 56 patients(36%) and LE or Nitrite were positive in 38 cases of 56 children with UTI(68%). 2)In microscopic analysis, WBC were positive in 38 cases of patients(68%) and bacteria were positive in 23 cases of 56 patients(41%) and WBC or bacteria were positive in 41 cases of 56 children with UTI(71%). 3)Ten cases of 56 UTI patients(18%) showed negative finding in Dipstick and microscopic analysis. 4)There was no significant difference in positive rate of dipstick(71% vs 66%) and microscopia analysis(83% vs 66%) between two group with or without renal scar on $^{99m}Tc-DMSA$ scan (P=0.117). 5)There was no significnt difference in positive rate of dipstick(100% vs 91%) and microscopic analysis(100% vs 100%) between two groups with or without vesicoureteral reflux on VCUG.
Conclusion : There was no specific relationships between the abnormal urinalysis and the abnormal findings on $^{99m}Tc-DMSA$ scan or VCUG.
